Direct electron- and hole-spin relaxation measurements in undoped piezoelectric CdTe quantum wells

Two heavy-hole exciton transitions sharing a common electronic energy level in the conduction band are used in a pump-probe transmission experiment to determine the spin relaxation time of both electrons and holes. In contrast with previous studies, we find that the hole spin relaxes more slowly tha...

Description
Summary:Two heavy-hole exciton transitions sharing a common electronic energy level in the conduction band are used in a pump-probe transmission experiment to determine the spin relaxation time of both electrons and holes. In contrast with previous studies, we find that the hole spin relaxes more slowly than the electron spin.
